  ILLUSTRATIVE 
  OF 
  

  

  While 
  the 
  trees 
  on 
  the 
  southern 
  edge 
  of 
  the 
  storm 
  were 
  thrown 
  

   generally 
  northward 
  and 
  eastward, 
  the 
  few 
  which 
  were 
  on 
  the 
  north 
  

   side, 
  were 
  thrown 
  to 
  the 
  southward. 
  Thus 
  at 
  i' 
  is 
  shown 
  a 
  large 
  

   black 
  cherry 
  tree, 
  uprooted 
  and 
  lying 
  nearly 
  parallel 
  to 
  the 
  side 
  

   of 
  the 
  house 
  A, 
  while 
  at 
  k' 
  and 
  1' 
  are 
  groups 
  of 
  willows, 
  the 
  limbs 
  

   of 
  which 
  were 
  broken 
  off, 
  and 
  thrown 
  to 
  the 
  southward 
  and 
  eastward. 
  

   There 
  were 
  no 
  trees 
  in 
  the 
  meadow 
  to 
  the 
  north 
  of 
  the 
  orchard 
  and 
  

   east 
  of 
  the 
  group 
  k'. 
  

  

  We 
  were 
  told 
  by 
  Mr 
  Polhemus 
  that 
  the 
  orchard 
  of 
  a 
  neighbour 
  to 
  

   the 
  west 
  of 
  him 
  had 
  been 
  prostrated, 
  but 
  did 
  not 
  consider 
  it 
  advisable 
  

   to 
  return 
  upon 
  that 
  point, 
  determining 
  rather 
  to 
  follow 
  the 
  track 
  of 
  the 
  

   storm 
  towards 
  Brunswick. 
  The 
  general 
  direction 
  of 
  Brunswick 
  from 
  

   Mr 
  Polhemus's 
  house 
  is 
  E 
  10° 
  N. 
  

  

  We 
  explored 
  the 
  wood 
  belonging 
  to 
  Mr 
  Polhemus, 
  and 
  eastward 
  

   from 
  his 
  dwelling, 
  where 
  the 
  marks 
  of 
  the 
  tornado 
  were 
  next 
  to 
  be 
  

   seen. 
  As, 
  however, 
  nothing 
  of 
  special 
  interest 
  was 
  developed, 
  I 
  have 
  

   not 
  thought 
  it 
  necessary 
  to 
  copy 
  the 
  drawing 
  made 
  from 
  my 
  notes. 
  

   Passing 
  through 
  this 
  wood, 
  the 
  track 
  was 
  marked 
  through 
  fields 
  of 
  grain 
  

   and 
  orchards 
  in 
  which 
  the 
  trees 
  were 
  uprooted, 
  and 
  near 
  buildings 
  

   which 
  suffered 
  more 
  or 
  less 
  from 
  its 
  action. 
  

  

  The 
  next 
  point 
  of 
  interest 
  occurred 
  where 
  we 
  distinctly 
  made 
  out 
  

   that 
  the 
  meteor 
  did 
  not 
  maintain 
  its 
  position 
  at 
  the 
  surface 
  of 
  the 
  

   ground 
  ; 
  a 
  fact 
  which 
  has 
  before 
  been 
  observed 
  in 
  regard 
  to 
  other 
  tor- 
  

   nadoes. 
  After 
  a 
  slight 
  damage 
  upon 
  the 
  edges 
  of 
  a 
  thick 
  wood 
  of 
  

   black 
  oak 
  trees, 
  the 
  marks 
  of 
  destruction 
  were 
  not 
  seen 
  until 
  traced 
  

   upon 
  a 
  ploughed 
  field, 
  to 
  the 
  east 
  of 
  the 
  wood, 
  in 
  which 
  there 
  were 
  a 
  

   few 
  trees. 
  These 
  were 
  uprooted, 
  and 
  the 
  moist 
  earth 
  from 
  the 
  sur- 
  

   face 
  of 
  the 
  field 
  was 
  thrown 
  against 
  the 
  trees 
  of 
  an 
  adjacent 
  wood. 
  

  

  The 
  next 
  diagram, 
  figure 
  4, 
  represents 
  a 
  very 
  remarkable 
  case, 
  esta- 
  

   blishing 
  conclusively 
  the 
  direction 
  of 
  the 
  forces 
  already 
  pointed 
  out 
  in 
  

   figure 
  2, 
  but 
  in 
  a 
  case 
  less 
  complicated 
  than 
  the 
  former. 
  

  

  In 
  a 
  tolerably 
  open 
  wood, 
  we 
  lost 
  all 
  traces 
  of 
  the 
  storm, 
  but 
  pur- 
  

   suing 
  a 
  general 
  easterly 
  direction, 
  came 
  upon 
  a 
  part 
  of 
  its 
  track 
  where 
  

   the 
  trees 
  were 
  broken 
  near 
  the 
  top. 
  A 
  little 
  further 
  on 
  they 
  were 
  

   broken 
  nearer 
  to 
  the 
  trunk, 
  and 
  at 
  last 
  uprooted.
